National Security Advisor Gen. Michael T. Flynn (ret.) — who resigned Monday — was the victim of a “hit job” launched by intelligence operatives, Obama government holdovers and former Obama national security officials, according to former intelligence officials who spoke with The Daily Caller News Foundation’s Investigative Group.

The talk within the tight-knit community of retired intelligence officers was that Flynn’s sacking was a result of intelligence insiders at the CIA, NSA and National Security Council using a sophisticated “disinformation campaign” to create a crisis atmosphere. The former intel officers say the tactics hurled against Flynn over the last few months were the type of high profile hard-ball accusations previously reserved for top figures in enemy states, not for White House officials.

“This was a hit job,” charged retired Col. James Williamson, a 32-year Special Forces veteran who coordinated his operations with the intelligence community.

Noting the Obama administration first tried to silence Flynn in 2014 when the former president fired him as director of the Defense Intelligence Agency, Williamson called Monday’s resignation, “stage Two of ‘Kill Mike Flynn.”

Former intelligence officials who understand spy craft say Flynn’s resignation had everything to do with a “disinformation campaign” and little to do with the December phone conversation he had with the Russian Ambassador Sergey Kislyak.
